Application led January 11, 1916. Serial No. 71,482.

To all whom ztimay concern.'

Be it known that I HUGO C. WELL, a subject of the German m eror, and a resident of the city of New lYor borough of Bronx,

in the count of Bronx and State of New York, have yinvented a new and Improved Carbureter, of which the following is a full, clear, and exact description.

My invention has for its object to provide a carbureter with a wick for conveying by capillary attraction a hydrocarbon to a passage where the air passing therefrom will entrain the h drocarbon.

Another obJect of the invention is to prol vide means for regulating the area of the air passage, as well asl the area of another air passage through which air may pass to be subsequently mixed with the air carrying the hydrocarbon.

Another object of the invention is to provide novel valve means for regulating the area of the two assages.

Still other ob]ects of the invention will appear in the following specification, in which the preferred form of my invention is disclosed.

In the drawings similar reference characters denote similar parts in all the views, in which- Y Figure 1 is a sectional view on the line 1-1 of Fig. 2;

Fig. 2 is a sectional view on the line 2 2 of Fig. 1;

Fig. 3 is a view of the rotatably mounted valve member;

Fig. 4 is a fragmentary view showing the indicating means for determinngthe position of the rotary valve member; and

Fig. 5 is a view showing the stationary lvalve member, which serves as a seat for the wick.

By referring to the drawings, it will be seen that the carbureter is constructed with a body 10 having a passage 11 with converging walls 12 for mixmg an explosive mixture with air in a manner which will hereinafter be described. This body 10 has a depending wall 13 and a depending threaded portion 14 with which meshes a thread 15 on a body member 16, this body member 16 having a circular wall 17 disposed concentrically with the wall 13 and spaced therefrom, to form a fountain 18 for the hydrocarbon. The member 16 at the bottom of its wall 17 is disposed inwardly at 19, forming a bottom for the fountain 18, the bottom 19 being, however,

spaced from the bottom of the circular wall 13 to form a passage 20 which leads to an annular canal 21 formed by the wall 13 and a concentric wall 22 which extends upwardly 60 from the bottom 19 of the member 16. This member 16 also has a circular wall 23 which extends upwardly from its bottom member 19, this circular wall 23 being substantially concentric with the wall 22, to form a passage 24 around a central passage 25 with Which the member 16 is provided and which 1s formed by the wall 23. The bottom 19 of the member 16 has openings 26 which lead to the passage 24, the bottom 19 being also 70 provided with a central opening 27 which leads to the passage ,25, the wall 23 adjacentl the opening 27 having a seat 28 against which is disposed a tube 29 to which is secured a rotary valve member 30.

This rotary valve member 30 is disposed on a seat 31 at the top of the wall 22, and is held in place by a valve member 32, which is disposed against the top of the rotary valve member 30 and is provided with a 80 thread 33 which meshes with a thread 34 in the wall 22.

The valve member 32 has a set of valve openings 35 which are disposed over the passage 24, the valve member 32 being also'85 provided with another set of valve openings 36 which are disposed over the passage 25, the valve openings 36 being staggered radially relatively to the valve openingsB. The vvalve member 30 has valve openings 37, each of which extends not only over the passage 24, but also over the passage 25, so that when this valve member 30 is rotated relatively to the valve member 32, the valve member 30 at its valve openings 37 will close one set 95 of the valve openings with which the valve member 30 is provided, while it opens the other set of valve openings in the valve member 32. The valve openings 37 and also the valve openings 35 and 36 are preferably provided with radially extending sides.

Disposed in the canal 21 there is a wick 38, this wick 38 extending inwardly and over the valve member 32, so that the wick will be disposed above the passage 24, but I prefer not to extend the wick above the passage 25. With this construction, the air which is drawn upwardly in the passage 24 by the operation of the piston in an internal combustion engine, will be drawn through the wick 38, and as this wick 38 extends below the level of the hydrocarbon in the fountain 18, the wickwill be saturated with hydrocarbon above the passage 24, and this hydrocarbon will be entrained with lthe air, which air charged with hydrocarbon will be d1- -rected inwardly by the coni/ er mg slde walls 12 at the passage l1, and will e mlxed with air passing' upwardly in the .central passage 25. There may be any deslred number of openings 39 in the wall 13 to'make csrtam that the wick 38 above the passage 24 1s saturated with the hydrocarbon all tunes, and the level of the hydrocarbon 1n the foun tain 18 may be maintained by any of the well known means.

Secured to the tube 29, there is an arm 40 which extends laterally and has secured to it a finger 41 which with a scale 42 may be used to determine the position of the valveA member 30 relatively to the valve member 32. The hydrocarbon is led to the fountain 18 through an opening 43 in the wall 17.
